Upserts match criteria for the audience's designated match column (the column used for enrichment matching). Match criteria define how audience column values are mapped to ZoomInfo attributes (for example, mapping an "Email" column to CONTACT_EMAIL) for enrichment resolution.

If a request body is provided, the supplied match criteria are applied directly — each entry maps an audience columnId to a ZoomInfo attribute field. If the request body is omitted or matchCriteria is not provided, the system attempts to auto-map match criteria using AI. If the match column does not exist, it will be created automatically.

Existing match criteria on the audience's match column are replaced by the new values. Returns 200 with the updated match column resource. Returns 400 if a columnId does not exist in the audience or a mappedTo value is invalid. Returns 404 if no audience matches the provided audienceId.
